I'm a junior web integrator, about to start
developing my first theme for Odoo's CMS. As stated in
the title, I'm looking for an adequate tool in order
to do so.

Jetbrains' IDEA family of IDEs seems to be
my thing, thanks especially to their good integration
of various frameworks' syntaxes, var/class memory,
etc. I've dug into JB repos and found no plugin that
could 'teach' them the dark ways of qWeb, which is
sad.

What would be your best advice, so as to
which I should use ? Is it delusional to hope for an
IDE-type experience ? Should I just bootstrap Sublime
with a few helpers and get going ?

As a bonus question, would you rather
recommend using v8 or v9c, given the latter's lack of
community extensions ?
